Landing a job straight into Asset Management, at least in the parts you probably want to be in, is tough. Not impossible, but tough. To begin with hours will be pretty rough (not too dissimilar to a sell side analyst), though there will be a fair few chances to go out to meetings, some conferences and stuff like that. Buyside pay is normally lower than sell-side, but has way better incentives involved to make it a better place to be in enough peoples minds.
You spend a lot of time looking at sectors or individual firms and putting a lot of thought into whether you should buy them, and if you already have them, whether you should sell them. Obviously, it becomes a lot more complicated than that, but that is generally your life - it just takes a fair amount of time to learn up to that point. That of course is fundamentals, you could become a quant and spend your life building a machine that does all that for you.
